First of all, get a real name and stop being a character. Its one thing to talk shit when nobody knows you. Its another to do it while using something that can identify you. We don't even know if you are NW or not, or just pretending you are because Jimma Snuka used to own a vacation home in such-and-such city.
You need to understand that telling someone to "rethink their career choice" is disrespectful, from any angle. I don't give a fuck HOW bad you think someone is. There are people that think my lyrics suck, but even more people IN REAL LIFE, not wearing masks or costumes, have told me to my FACE that I have that shit. People have also told me of other people saying these things--3rd party props.
This same thing may be the case with our friend Robo. I don't know. What I do know is that being mad at a man for doing something in another thread, is no reason to do the same thing to him, and then claim you're only doing it because A, B and C. It matters not. If it was poor judgement then, then you exhibited even POORER judgement for doing the same.
In conclusion, this man no more needs to put up his "tightest beat" than I need to break out a tight song I have yet to release. You will wait for this man to release his beats like anyone else. If that isn't good enough for you...who cares.
